The shack is easy to erect and the sewn in ground sheet is also raised so that it touches the base of the van, eliminating any draughts. I use this on days out to the countryside effectively extending the living accommodation at the rear of the camper van. At night, I erect a tailgate awning on top to provide further space, but this takes much longer and can only be used when there is time and space and requires pegs. The packashack can be erected anywhere, and quickly. You can also use weighty items to secure the corners from the inside so pegs are not needed. The shack is well made and the only product I have found that has the combination of qualities that I was looking for. Nothing else like it.
